My pointer zones are more like Zone "28.66.136.193.in-addr.arpa.", I've never had that leading "0-"
Is that typical? What does it do? -----Original Message----- From: bind-users <bind-users-boun...@lists.isc.org> On Behalf Of Grant Taylor via bind-users Sent: Friday, November 4, 2022 1:07 PM To: bind-users@lists.isc.org Subject: Re: Reverse lookups not working when Internet connection failed.

This is > getting complicated 😉 So when your system(s) try to do a reverse DNS (PTR) lookup for 193.136.66.1, it will actually do a PTR lookup for 1.66.136.193.in-addr.arpa. and fail because you don't have a copy of the 66.136.193.in-addr.arpa. zone file locally. At least my understanding is that you have a copy of your forward zone, and your 0-28.66.136.193.in-addr.arpa. zone. But you don't have a copy of, nor access to, the intermediate 66.136.193.in-addr.arpa. zone that references the 0-28.66.136.193.in-addr.arpa. zone. Does that help?
